In this Bling Advisor article, we will review the correlation between diamond shapes and prices.
How Does Diamond Shape Affect Price?
A variety of elements determines the price of a diamond. One of these factors is the shape, also known as the cut; different shapes cost different prices as they have different characteristics that make them more or less desirable for certain people.
Other factors that might affect a diamond’s price are size, scintillation, pattern, and brilliance.
Why does Diamond Price vary depending on its shape?
There are many different diamond shapes, each with a different price range.
Different diamond shapes provide different characteristics that suit different purposes. Grooms and brides looking for engagement rings will prefer specific shapes and therefore be willing to pay more for them. That alters the demand, which in turn alters the price of that particular shape.
Generally speaking, the more rare a diamond shape is, the higher its price will be because people value things that aren’t easily accessible and lack many substitutes. That is true for diamonds as well as many other things.
This article lists the 11 most common diamond shapes, from the most popular and expensive to the most affordable diamond cut.
